The day before yesterday afternoon, the director of the Public Security Bureau received a letter, still in printed font, which read: I am a sick person, and I am resenting the Public Security Bureau for this disease, and you will regret your despicable crimes. I have already planted bombs elsewhere as well, and the night after tomorrow I will deal a heavy blow to the city.

After Qiao Yan entered the banquet hall, she immediately met Mo Yuqing, who was sitting on the sofa waiting. Mo Yuqing wore a water-red evening dress, like a delicate rose. Both of them have miniature communicators hidden on their bodies, and Zeng Jinling's voice came through the headset: "I have sent you the criminal notice and the bomb photos I received earlier." The prisoners who planted the bombs were lurking in this venue. There are less than 20 minutes left before the explosion notice. Zeng Jinling and Wan Xing had already entered the banquet hall first, hidden in a conference room, where there was surveillance equipment, and they could clearly see all corners of the banquet hall. Wanxing is responsible for operating the computer, and Zeng Jinling is in charge of the overall situation.

Qiao Yan and Mo Yuqing each looked down at their mobile phones, and the crime notice was the content of the letter received by the public security chief.

"The name and appearance of the target are unknown, how are you going to arrest him?" Wei Chihong didn't know when he went downstairs and came to Qiao Yan's side, he was talking to Qiao Yan, but his keen eyes roamed the entire banquet hall.

"It is enough to have a criminal notice of the offender." Qiao Yan analyzed, "Judging from the method of making bombs, it is certain that F· P is for a man and not a woman. There is no doubt that this man was prejudiced against the Public Security Bureau, which he believed was causing him to be ill. Gradually, he felt that the whole world could not get along with him, which was the reason for his abnormal behavior. Once a person is entangled in this thought, he becomes paranoid.

According to psychologists, paranoia develops slowly, but after the age of 35, it develops out of control. That F· P should be over 35 years old. According to a German psychiatrist, 85% of paranoid patients are athletes. F· P should not be fat or thin, of medium stature, and have a well-proportioned physique. ”

"Such a person should maintain his gentlemanly demeanor and pay attention to neat dressing, but he is hesitant to change the style." Mo Yuqing added, "The men who went to the banquet today were all wearing suits, and he should be wearing the most ordinary and old-fashioned tops, with neat buttons. His hair was combed bare, and he wore all-purpose black leather shoes, polished and shiny. ”

"I agree with both of them." Zeng Jinling reported to Wei Chihong through communication equipment, "There are still 10 minutes before the explosion, how about it, can you find that person?" ”

"There are too many men, at least more than 100 people, and it is impossible to check and observe the physical characteristics one by one." Wei Chihong denied this approach.

"In that case, it's okay to check the woman." Qiao Yan reacted quickly, "For prisoners, an explosion is like setting off fireworks. Like F· People like P must have suffered some kind of psychological trauma. For example, his mother has long since died, and this tragedy is his father's fault. The loss of his mother's love made him feel painful, and in his later life, there was no one to give him love or friendship, and his psychological wounds never healed.

I dare to conclude that he is a celibate. However, he may be living with a female relative who is older than him. This female relative reminded him of his mother, thus touching his resentment towards his father, which in turn inspired him to rebel against authority. That's why he dropped the bomb. Watching the explosion with the female relative, F· P, it must be a lot of fun. ”
